A Session object is a single-threaded context for producing and consuming messages. Although it may allocate provider resources outside the Java virtual machine (JVM), it is considered a lightweight JMS object.
A session serves several purposes:
- It is a factory for its message producers and consumers.
- It supplies provider-optimized message factories.
- It is a factory for TemporaryTopics and TemporaryQueues.
- It provides a way to create Queue or Topic objects for those clients that need to dynamically manipulate provider-specific destination names.
- It supports a single series of transactions that combine work spanning its producers and consumers into atomic units.
- It defines a serial order for the messages it consumes and the messages it produces.
- It retains messages it consumes until they have been acknowledged.
- It serializes execution of message listeners registered with its message consumers.
- It is a factory for QueueBrowsers.
A session can create and service multiple message producers and consumers.
One typical use is to have a thread block on a synchronous MessageConsumer until a message arrives. The thread may then use one or more of the Session'sMessageProducers.
If a client desires to have one thread produce messages while others consume them, the client should use a separate session for its producing thread.
Once a connection has been started, any session with one or more registered message listeners is dedicated to the thread of control that delivers messages to it. It is erroneous for client code to use this session or any of its constituent objects from another thread of control. The only exception to this rule is the use of the session or connection close method.
It should be easy for most clients to partition their work naturally into sessions. This model allows clients to start simply and incrementally add message processing complexity as their need for concurrency grows.
The close method is the only session method that can be called while some other session method is being executed in another thread.
A session may be specified as transacted. Each transacted session supports a single series of transactions. Each transaction groups a set of message sends and a set of message receives into an atomic unit of work. In effect, transactions organize a session's input message stream and output message stream into series of atomic units. When a transaction commits, its atomic unit of input is acknowledged and its associated atomic unit of output is sent. If a transaction rollback is done, the transaction's sent messages are destroyed and the session's input is automatically recovered.
The content of a transaction's input and output units is simply those messages that have been produced and consumed within the session's current transaction.
A transaction is completed using either its session's commit method or its session's rollback method. The completion of a session's current transaction automatically begins the next. The result is that a transacted session always has a current transaction within which its work is done.
The Java Transaction Service (JTS) or some other transaction monitor may be used to combine a session's transaction with transactions on other resources (databases, other JMS sessions, etc.). Since Java distributed transactions are controlled via the Java Transaction API (JTA), use of the session's commit and rollback methods in this context is prohibited.
The JMS API does not require support for JTA; however, it does define how a provider supplies this support.
Although it is also possible for a JMS client to handle distributed transactions directly, it is unlikely that many JMS clients will do this. Support for JTA in the JMS API is targeted at systems vendors who will be integrating the JMS API into their application server products.

  - close
```
public void close()
           throws javax.jms.JMSException
```
    Closes the session.
    Since a provider may allocate some resources on behalf of a session outside the JVM, clients should close the resources when they are not needed. Relying on garbage collection to eventually reclaim these resources may not be timely enough.
    There is no need to close the producers and consumers of a closed session.
    This call will block until a receive call or message listener in progress has completed. A blocked message consumer receive call returns null when this session is closed.
    Closing a transacted session must roll back the transaction in progress.
    This method is the only Session method that can be called concurrently.
    Invoking any other Session method on a closed session must throw a JMSException.IllegalStateException. Closing a closed session must not throw an exception.
    
    Specified by:

  - recover
```
public void recover()
             throws javax.jms.JMSException
```
    Stops message delivery in this session, and restarts message delivery with the oldest unacknowledged message.
    All consumers deliver messages in a serial order. Acknowledging a received message automatically acknowledges all messages that have been delivered to the client.
    Restarting a session causes it to take the following actions:
    - Stop message delivery
    - Mark all messages that might have been delivered but not acknowledged as "redelivered"
    - Restart the delivery sequence including all unacknowledged messages that had been previously delivered. Redelivered messages do not have to be delivered in exactly their original delivery order.
    Specified by:

```
    Sets the session's distinguished message listener (optional).
    When the distinguished message listener is set, no other form of message receipt in the session can be used; however, all forms of sending messages are still supported.
    If this session has been closed, then an IllegalStateException is thrown, if trying to set a new listener. However setting the listener to null is allowed, to clear the listener, even if this session has been closed prior.
    This is an expert facility not used by regular JMS clients.

    Creates a queue identity given a Queue name.
    This facility is provided for the rare cases where clients need to dynamically manipulate queue identity. It allows the creation of a queue identity with a provider-specific name. Clients that depend on this ability are not portable.
    Note that this method is not for creating the physical queue. The physical creation of queues is an administrative task and is not to be initiated by the JMS API. The one exception is the creation of temporary queues, which is accomplished with the createTemporaryQueue method.

```
    Creates a durable subscriber to the specified topic.
    If a client needs to receive all the messages published on a topic, including the ones published while the subscriber is inactive, it uses a durable TopicSubscriber. The JMS provider retains a record of this durable subscription and insures that all messages from the topic's publishers are retained until they are acknowledged by this durable subscriber or they have expired.
    Sessions with durable subscribers must always provide the same client identifier. In addition, each client must specify a name that uniquely identifies (within client identifier) each durable subscription it creates. Only one session at a time can have a TopicSubscriber for a particular durable subscription.
    A client can change an existing durable subscription by creating a durable TopicSubscriber with the same name and a new topic and/or message selector. Changing a durable subscriber is equivalent to unsubscribing (deleting) the old one and creating a new one.
    In some cases, a connection may both publish and subscribe to a topic. The subscriber NoLocal attribute allows a subscriber to inhibit the delivery of messages published by its own connection. The default value for this attribute is false.

                                           throws javax.jms.JMSException
```
    Creates a nondurable subscriber to the specified topic.
    
    A client uses a TopicSubscriber object to receive messages that have been published to a topic.
    
    Regular TopicSubscriber objects are not durable. They receive only messages that are published while they are active.
    
    In some cases, a connection may both publish and subscribe to a topic. The subscriber NoLocal attribute allows a subscriber to inhibit the delivery of messages published by its own connection. The default value for this attribute is false.
    
    Specified by:
    
    createSubscriber in interface javax.jms.TopicSession
    
    Parameters:
    
    topic - the Topic to subscribe to
    
    Returns:

                                           throws javax.jms.JMSException
```
    Creates a nondurable subscriber to the specified topic, using a message selector or specifying whether messages published by its own connection should be delivered to it.
    
    A client uses a TopicSubscriber object to receive messages that have been published to a topic.
    
    Regular TopicSubscriber objects are not durable. They receive only messages that are published while they are active.
    
    Messages filtered out by a subscriber's message selector will never be delivered to the subscriber. From the subscriber's perspective, they do not exist.
    
    In some cases, a connection may both publish and subscribe to a topic. The subscriber NoLocal attribute allows a subscriber to inhibit the delivery of messages published by its own connection. The default value for this attribute is false.
    
    Specified by:
    
    createSubscriber in interface javax.jms.TopicSession
    
    Parameters:
    
    topic - the Topic to subscribe to
    
    messageSelector - only messages with properties matching the message selector expression are delivered. A value of null or an empty string indicates that there is no message selector for the message consumer.
    
    noLocal - if set, inhibits the delivery of messages published by its own connection
    
    Returns:
    
    TopicSubscriber
    
    Throws:
    
    javax.jms.JMSException - if the session fails to create a subscriber due to some internal error.
    
    javax.jms.InvalidDestinationException - if an invalid topic is specified.

                                         throws javax.jms.JMSException
```
    Creates a publisher for the specified topic.
    
    A client uses a TopicPublisher object to publish messages on a topic. Each time a client creates a TopicPublisher on a topic, it defines a new sequence of messages that have no ordering relationship with the messages it has previously sent.
    
    Specified by:
    
    createPublisher in interface javax.jms.TopicSession
    
    Parameters:
    
    topic - the Topic to publish to, or null if this is an unidentified producer
    
    Returns:
    
    TopicPublisher
    
    Throws:
    
    javax.jms.JMSException - if the session fails to create a publisher due to some internal error.
    
    javax.jms.InvalidDestinationException - if an invalid topic is specified.
  - unsubscribe
```
public void unsubscribe(String name)
                 throws javax.jms.JMSException
```
    Unsubscribes a durable subscription that has been created by a client.
    This method deletes the state being maintained on behalf of the subscriber by its provider.
    It is erroneous for a client to delete a durable subscription while there is an active MessageConsumer or TopicSubscriber for the subscription, or while a consumed message is part of a pending transaction or has not been acknowledged in the session.
    
    Specified by:
    
    unsubscribe in interface javax.jms.Session
    
    Specified by:
    
    unsubscribe in interface javax.jms.TopicSession
    
    Parameters:
    
    name - the name used to identify this subscription
    
    Throws:
    
    javax.jms.JMSException - if the session fails to unsubscribe to the durable subscription due to some internal error.
    
    javax.jms.InvalidDestinationException - if an invalid subscription name is specified.

    dispatch in interface ActiveMQDispatcher
  - acknowledge
```
public void acknowledge()
                 throws javax.jms.JMSException
```
    Acknowledges all consumed messages of the session of this consumed message.
    All consumed JMS messages support the acknowledge method for use when a client has specified that its JMS session's consumed messages are to be explicitly acknowledged. By invoking acknowledge on a consumed message, a client acknowledges all messages consumed by the session that the message was delivered to.
    Calls to acknowledge are ignored for both transacted sessions and sessions specified to use implicit acknowledgement modes.
    A client may individually acknowledge each message as it is consumed, or it may choose to acknowledge messages as an application-defined group (which is done by calling acknowledge on the last received message of the group, thereby acknowledging all messages consumed by the session.)
    Messages that have been received but not acknowledged may be redelivered.
    
    Throws:
    
    javax.jms.JMSException - if the JMS provider fails to acknowledge the messages due to some internal error.
    
    javax.jms.IllegalStateException - if this method is called on a closed session.
